GAS GOVERNOR AND REGULATOR FOR CARBURETERS.

SPECIFICATION forming part of Letters Patent No. 230,744, dated August3, 1880.

Application filed April 17, 1880.

To all whom it may concern:

Be it known that I, ALBERT F. OHAoE, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Gas Governors and Regulators for Oarbureters; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and-operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical section of mygas governor and regulator, and Fig. 2 is a view of a modification ofthe lever.

This invention has relation to gas governors and regulators forcarbureters; and it consists in the improvements in the construction ofthe same, hereinafter fully described, and particularly pointed out inthe claims.

Referring by letter to the accompanying drawings, A designates thecarbnreting-chamber, B the reservoir for the hydrocarbon liquid, and Othe inlet-pipe from the reservoir B to the carbureting-chamber A. Thepipe 0 is provided with a stop-cock, D, as shown, and in the mouth ofthe upturned elbow of this inletpipe 0, and at its termination in thecarburetin g-chamberA, is placed avalve-seat, E or the pipe mayterminate in a valve-seat. Around the pipe 0, at its termination withinthe carbureting-chamber A, is placed a perforated pan, F, through whichthe hydrocarbon liquid passes to the carbureter.

From the head G of the carbureting-chamher A depends an arm, H, to whichis pivoted a hinged lever, I, the joint in the said lever being made atthe right-hand side of the arm H. Upon the upper face of the portion Iof the hinged lever I is fixed a flat spring, J ,which extends over uponand presses against the upper face of the arm 1 of the lever I. The armI of the lever I is provided with a needle, K, secured to or formed witha screw-shank, L, which is screwed into a threaded hole in the end ofthe arm I of said lever I.

Above the carbureting-chamber A is a gasgovernor, M, the valve-chamber Nof which is secured to a collar, 0, upon the head of the chamber A bybolts or otherwise. The valve- (No model.)

chamber N opens into the gas-chamber P through the valve-seat Q. Nearthe top of the gas-chamber is the mercury-cup Pt, and over this isplaced an inverted cup, S. To the diaphragm is clamped, by screw-nuts aa, the upper end of the rod T, from which a weighted conical-shapedvalve, U, is suspended by a link-connection, so that the valve U mayturn when the rod T is turned by a wrench or otherwise at the upper end.From the lower side of the weighted valve U a screw-threaded rod, V,enters and penetrates for adistance a little greater than the length ofthe needle K. The lower end of the rod V is pivoted to the end of theportion I of the hinged lever I, as shown.

In Fig. 2 of the drawings a modification of the hinged lever I is shown,and it consists in making the hinged portion 1 in the form of a flatspring, I/V, thereby dispensing with the hinge. In other respects it isintended to be entirely similar.

In operation this device can either be made automatic, or it may becontrolled by the operator to suit the circumstances under which it maybe necessary to use it. The main object is, however, to control the flowof the hydrocarbon liquid to the carbureter, so as to leave thevalve-seat open for any length of time, or to cut off the supply of saidliquid by keeping the valve closed for any desired length of time,Without interfering with the flow of gas from the carbureter through thegas-governor to the burners.

If properly adj usted,the device will work automatically and feed thehydrocarbon liquid to the carbureter in just such quantitiesas may beneeded to supply the gas to one or more burners. If, however, it shouldbe desired to supply a large number of burners and a continuous flow ofthe hydrocarbon liquid should be necessary to carburet the air or gas,the rod T should be turned at the nut a by first removing the cap X tothe governor-casing, so as to cause the valve U to ascend the threads onthe rodVandcause the portion I of the lever I to be depressed, whichwould cause the needle K to be withdrawn from the valve-seat, and wouldpermit a continuous flow of the hydrocarbon liquid to the carb ureter,so that a larger quantity of gas would be carbureted and fed to theburners.

If, however, the supply should become sufficiently great, and it shouldbe necessary to stop the flow of the hydrocarbon liquid to thecarbureter, by turl'iing the rod T to cause the conical valve U todescend upon the rod V the lever I would be operated to cause the needleK to be depressed and made to enter and tightly close the valve-seat E,and thereby effectually cut off the flow of the hydrocarbon liquid tothe carbureter. At the same time, however, the gas already in thecarbnreter, if of sufficient power, which need not exceed fourteenpounds pressure in an ordinary apparatus, would operate thegas-governor, by reason of the fact that the hinged joint and the springJ of the lever I make so little resistance as to permit the valve to becarried up and operated to feed the gas to the burners for aconsiderable period of time after the supply of hydrocarbon liquid hasbeen out off from the carbureter.

It should be noticed that when the valve is turned to depress the rod V,or when the device is operated automatically, that the shoulders of thejoint in the lever cause the lever to operate to elevate the needle,while, when this operation is reversed, the spring J, bearing upon thearm 1 causes the needle K to enter the opening in the valve-seat E.

I am aware that an automatic feed-regulator for carbureters consistingof an independent automatic gas-governor having its valve connecteddirectly to and combined with the valve or cock of the hydrocarbon-pipefor a constant unison of action, whereby the respective flows of the gasand hydrocarbon are made always to maintain a constant and uniformrelation to each other independently of the carbureting apparatus, isnot new, as the same is shown in Patent No. 198,353, of December18,1877.

I am also aware that a vibrating lever carrying a needle-valve workingin the oil-induct pipe and a conical valve working in the gasinduct pipehas been employed, as shown in Patent No. 212,502, of February 18, 1879,and that the air-injecting valve and the valve in the gasoline-feed pipeofacarbureter have been operated automatically by the rising and fallingaiuholder, and I make no broad claim to either of these constructionsherein.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a gas governor and regulator for carbureters, the combination of areversely-adjustable valve in the gas-governor with a pivoted hingedspring-lever in the carbureter, said lever being provided with a needlefor opening and closing a valve-seat, and avalve-seat located in themouth of the inlet-pipe, through which the hydrocarbon liquid issupplied to the carbureter, as set forth.

2. In a gas governor and regulator for carbureters, the valve U,suspended from the cup S by the rod '1, and provided with the screwrodV, in combination with the hinged and pivoted lever I I I carrying theneedle K, and the valve-seat E in the mouth of the pipe 0, substantiallyas and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
